Not sure if you still have them cards Motorolin', but here's a "trick" for the lazy-to-desolder:
Take a sharp-ish knife and try to cut the chips at their legs. Because you don't care about the rest of the card (I assume this is true anyways), you can use the card as a "guide", so you're basically angling the knife at around 45 degrees from the card and towards the base of the chip legs. The card surface will get all scratched up, but before you know it you'll have the one side of the chip cut clean. You repeat on the other, and then you'll have those "desoldered" chips on your hands. Just clean'em up a bit, maybe with a file if there are any sharp edges, and maybe straigthen out a pin or two that might have been bent, and they're as good as new. Used to do that years ago to upgrade *socketed* (that's the trick, coz these chips can't be easily soldered once they're cleaved) PCI cards with more memory
Good luck
